This unit combines skills originally covered by Edexcel's SoW modules: Edexcel module 1-16, Edexcel module H1.9 and Edexcel module H2.1.
The References, Prior Learning, Key Objectives, Differentiation and Notes are drawn together summatively from these Edexcel modules.

GCSE GM2 - perimeter area and volume

grade	level	learning objective	learning activity
A*	10	¨Tackle problems that bring together different aspects of mathematics and may involve multiple variables. Identify some variables and investigate them systematically; the outcomes of which are used in solving the problem.
A*	10	¨identify and use mathematics accurately in a range of contexts; choose methods of mathematical communication appropriate to the context.
